Ion chromatography is a process in which ions and polar molecules are separated based on their charge. This can be done with most any type of charged molecule.
In the case of liquid sample, take known amount of sample filter through 0.2µm; 47mm filter paper using suction pump.
In the case of solid samples, take known amount of sample and dissolved suitable acid/base then adjust the pH around 6.5 to 7.5 of the dissolved sample. Finally sample filter through 0.2µm; 47mm filter paper using suction pump.
